2 Methods of stressing U-bend specimens
This covers procedures for designing, preparing and using U bend test specimens for investigating the susceptibility of a metal to stress corrosion. U bend specimens may be used to test a variety of product forms. They are used for sheet, plate or flat extruded material, which conveniently provides flat specimens of rectangular cross section, but may be employed for wire or rod, or for machined specimens of circular cross section. Can be used for parts joined by welding. The U bend test is used to establish whether a metal is susceptible to stress corrosion cracking in a given environment.
